About TIM1 in STM8L series. I have been trying default PWM testcase available by STM for modulating Duty channel and frequency. I change values of TIM_PERIOD and CCRx_Val. I only see frequency changing. For some reason I observe only 50% duty cycle.

[RShah.3]

For some reason I am not able to see pins behavior in plotter. I am not able to see PD 2,4,5 output on plotter on STVD tool.

I got the testcase from https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm8-embedded-software/stsw-stm8016.html

Testcase name and path -

C:\STM8L15x-16x-05x-AL31-L_StdPeriph_Lib\Project\STM8L15x_StdPeriph_Examples\TIM1\TIM1_PWMOutput

Thanks in advance.

Also let me know if you need more details for the question.
